I want to add simple search bar in the table view. Program getting run with no error, but when I try to add text in search bar, program gets terminates
following is my code:

I have a problem that Im sure many objectiveC developers would be able to solve pretty easily. Im developing an app which is a dynamic tableview with different groups that the user can create. The user can enter a number of groups with different totals. I am trying to sum the total of all the groups created.
The IBAction I am using to calculate the subtotal is
- (IBAction)Calculate:(id)sender {
//---------------
NSInteger Tempsum = [[_dataArray valueForKeyPath:#"#sum.name2"] integerValue];
_TotalAnimals.text = [[NSString alloc] initWithFormat:#"%.1ld", (long)Tempsum];
//--------------
}
I have created the following code in the .m file of my tableview and also created a NSArray property called;
#property NSArray *dataArray;
however I am unsure as to the correct code to use to be able to link the result ( #"#sum.name2" ) to the text value in the Tableviewcontroller ( _TotalAnimals.text)
Any help with this problem would be much appreciated. below is the full code for the .m file
#import "TSPViewController.h"
#import <CoreData/CoreData.h>
#import "TSPToDoCell.h"
#import "TSPAddToDoViewController.h"

I have several CoreDataTableViewControllers that utilize the helper class from Paul Hegarty's course. Everyone of them works except this one, and I cannot see a difference.
When the table first comes up, it is correctly populated and the segue executes properly when a cell is selected. However when I hit the back button, the table displays (null), (null) everywhere.
I have tried every variant of calling [self useDocument] that I can think of, still to no avail. Any thoughts? Thanks in advance.

Well, I am not certain what the problem was. I ended up deleting the "offending" TableViewControllers in StoryBoard and recreated them. That did the trick. In retrospect, I wonder if I did not specify the wrong type of segue from my tabViewController. But I deleted it before I thought of that possibility.
I used core data to set up all of my entities. But when I try to create a new customer entity and send it to the modal addCustomer view controller I keep getting this error.
* Terminating app due to uncaught exception
'NSInvalidArgumentException', reason: '-[UINavigationController

The error occurs in AccountListTableViewController.m when the program gets to addController.customer = newCustomer in the prepareForSegue.

Are you sure your destination view controller is a CustomerAddViewController?
It looks like it's actually a navigation controller. Hence the [UINavigationController setCustomer:]: unrecognized selector sent to instance 0x8854700 when you do addController.customer = newCustomer
In continuation to the first answer, the correct way to then reach the destination view controller when a navigation controller is between is as follows
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([segue.identifier isEqualToString:#"AddAccountSegue"])
{
UINavigationController *navigationController = segue.destinationViewController;
CustomerAddViewController *addController = (id)[[navigationController viewControllers] objectAtIndex:0];
[addController setCustomer:yourObject];
}
}

The problem is I am getting a warning with the following line:
tempArr = self.fetchedResultsController.fetchedObjects;
The warning is: "/Users/satyam/Desktop/EmployeeDetails/Classes/RootViewController.m:43:0 /Users/satyam/Desktop/EmployeeDetails/Classes/RootViewController.m:43: warning: incompatible Objective-C types assigning 'struct NSArray *', expected 'struct NSMutableArray *'"
Just read the warning word for word.
you try to assign an NSArray to a variable that expects a NSMutableArray.
self.fetchedResultsController.fetchedObjects is an NSArray
tempArr is an NSMutableArray
but if you use the NSFetchedResultsController you don't need your own data array at all.
The NSFetchedResultsController handles all the data for you.
so maybe you want to replace
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
if([self.array count])
{
return [array count];
}
return 1;
}
with
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
id <NSFetchedResultsSectionInfo> sectionInfo = [[self.fetchedResultsController sections] objectAtIndex:section];
return [sectionInfo numberOfObjects];
}
your own datasource is invalid anyway. because you assign the sortDescriptor used for the NSFetchedResultsController to it.
NSMutableArray *sortDescriptors = [[NSMutableArray alloc] initWithObjects:nameDescriptor, idDescriptor, nil];
self.array = sortDescriptors;
I don't know what you wanted to achieve by doing this.
I have an app that has a tab bar, each tab contains a separate table. The first table uses core data to persist its entries and checkmarks. The second table on the second tab uses an NSMutableArray to populate it (I would use core data but I would have to pre populate it and this table does not allow that) I would like to persist check marks the same way I do in the first table with core data but something is wrong. The code looks like this:
-(void)viewDidLoad {
[super viewDidLoad];
airport = [[NSMutableArray alloc] init];
[airport addObject:#"Passport"];
}
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
// Customize the number of rows in the table view.
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [airport count];
}
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
// Set up the cell...
NSString *cellValue = [airport objectAtIndex:indexPath.row];
cell.textLabel.text = cellValue;
//[cell setAccessoryType:UITableViewCellAccessoryDisclosureIndicator];
NSManagedObject *item = [[self fetchedResultsController] objectAtIndexPath:indexPath];
cell.textLabel.text = [item valueForKey:#"name"]; //CHANGED TO DETAIL
if ([[item valueForKey:#"check"] boolValue]) {
cell.accessoryType = UITableViewCellAccessoryCheckmark;
} else {
cell.accessoryType = UITableViewCellAccessoryNone;
}
cell.selectionStyle = UITableViewCellSelectionStyleNone;
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
NSManagedObject *selectedObject = [self.fetchedResultsController objectAtIndexPath:indexPath];
if ([[selectedObject valueForKey:#"check"] boolValue]) {
[selectedObject setValue:[NSNumber numberWithBool:NO] forKey:#"check"];
} else {
[selectedObject setValue:[NSNumber numberWithBool:YES] forKey:#"check"];
}
UITableViewCell *thisCell = [tableView cellForRowAtIndexPath:indexPath];
if (thisCell.accessoryType == UITableViewCellAccessoryNone) {
thisCell.accessoryType = UITableViewCellAccessoryCheckmark;
} else {
thisCell.accessoryType = UITableViewCellAccessoryNone;
}
[tableView deselectRowAtIndexPath:indexPath animated:NO];
}
I believe the line cell.textLabel.text = [item valueForKey#"name"];
is whats causing it. All that I would like for this to do is have the table populated from the array and check marks persisted. Any help is GREATLY appreciated. Thanks in advance.
This line is replacing the cell text:
cell.textLabel.text = [item valueForKey:#"name"];
that was initially assigned by these lines:
NSString *cellValue = [airport objectAtIndex:indexPath.row];
cell.textLabel.text = cellValue;
Why are your using the "name" property of "item"?
